OpenAI’s ChatGPT Returns to Italy after Addressing Data Privacy Concerns

OpenAI, the creator of ChatGPT, has recently returned to the Italian market after addressing the data protection authority’s concerns regarding the AI chatbot’s compliance with regional data protection laws. The Garante had temporarily blocked access to ChatGPT in Italy on March 31, 2023, but reinstated the service after OpenAI made the required changes. The company has published a new FAQ detailing its data filtering and removal practices, as well as its commitment to not using personal information in any malicious manner.

Google Takes Legal Action Against CryptBot Malware

Google has obtained a temporary court order in the U.S. to disrupt the distribution of the Windows-based information-stealing malware, CryptBot, which has infected over 670,000 computers in 2022. The malware, first discovered in 2019, steals sensitive data such as authentication credentials, social media account logins, and cryptocurrency wallets from Google Chrome users. Google aims to use the court order to take down current and future domains linked to CryptBot distribution, ultimately curtailing the malware’s spread. To mitigate the risks posed by such threats, users are advised to download software only from trusted sources and keep their devices and software up-to-date.

The group behind RTM Locker is known for avoiding high-profile targets, utilizing affiliates to ransom victims, and leaking stolen data if ransom demands are not met. However, the initial infection vector for the ransomware is still unknown.
